Premixed flow state filling material of easily-weathered rock aggregate
The invention discloses a premixed flow state filling material of easily-weathered rock aggregate, which is formed by jointly mixing easily-weathered rock such as limestone, shale, sandstone, schist and phyllite, aggregate composed of bentonite and collapsible loess, a curing agent, an additive and water, and the aggregate is composed of fine aggregate and coarse aggregate. According to the mixed filling material, common engineering soil in the northwest region is used as a raw material, and the mixed filling material which is weak in shrinkage performance, low in consolidation settlement, free of collapsibility, low in permeability, capable of meeting the bearing capacity requirement and low in price and takes the easily-weathered rock as the main body in the backfilling process is provided.
本发明公开了一种易风化岩集料的预拌流态填充材料，由灰岩、页岩、砂岩、片岩、千枚岩等易风化岩和膨润土、湿陷性黄土构成的集料、固化剂、外加剂、水共同混合组成，所述集料由细集料和粗集料组成。本发明结合西北地区较为常见工程土为原材料，提出了一种在回填过程中收缩性能弱、固结沉降低、无湿陷性、渗透性能低、承载能力满足要求且价格低廉的以易风化岩为主体的混合填筑材料。
